Abstract
The utility model discloses a steel tube screw thread sand-blasting machine withdrawing port sealing device which comprises an air pump (2), an air pumping pipeline (3), a compressed air pipeline (4), an air blowing device (5), an air sucking device (7) and a soft resin sealing device (8), wherein the compressed air pipeline (4) extends into the air blowing device (5); the air blowing device (5) and the air sucking device (7) are sleeved at the periphery of a steel tube (6) and are sealed up by the soft resin sealing device (8); the air blowing device (5) is provided with an annular blowing port towards the air sucking device (7); the air pump (2) is communicated with the air sucking device (7) through the air pumping pipeline (3). When the steel tube (6) is subjected to sand blasting, the air blowing device (5) and the air sucking device (7) are started, the compressed air pipeline (3) enters an empty bag of the air blowing device (5), then the empty bag of the air blowing device (5) is in the high-pressure state, an annular air curtain which is ejected towards the air sucking device (7) is formed through the annular blowing port so as to blow sand powder adhered to the surface of the steel tube off from the steel tube, and meanwhile the air sucking device (7) sucks the sand powder flying in the air into the air pumping pipeline and feeds the sand power to the air pump. The steel tube screw thread sand-blasting machine is good in sealing effect and beneficial to mounting and maintenance of devices and no sand powder is adhered to the surface of the steel tube after sand blasting.
Description
Technical field
The utility model relates to a kind of steel pipe screw thread sand-blasting machine and withdraws from mouth sealing device, belongs to the steel pipe's production field.
Background technology
At present, in the seamless steel pipe processing, for the requirement of certain user and standard, need to carry out blasting treatment to the screw thread of steel pipe.The sand powder that sandblast is adopted is extremely tiny, if seal badly, unfavorable to the steel pipe subsequent technique, and can pollute site environment, increases the fault rate of field apparatus, infringement field worker healthy.Because withdrawing from port part, sand-blasting machine need to pass in and out steel pipe, so sand-blasting machine withdraws from the key that the sealing of port part seals success or not especially.Sand-blasting machine in the past withdraws from port part, and the method that generally adopts barras sealing or barras sealing to combine with negative inspiratory pressure can not be removed the fine sand powder that steel tube surface adheres to fully, and sealing effectiveness is relatively poor.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provides a kind of steel pipe screw thread sand-blasting machine to withdraw from mouth sealing device, is used for the Production Line of Pipe Finishing sand-blasting machine and withdraws from port part.This device mainly partly is comprised of air exhauster 2, exhaust pipe 3, compressed air line 4, blowning installation 5, getter device 7, barras sealing device 8 etc., and compressed air line 4 stretches in the blowning installation 5.Blowning installation 5 and getter device 7 are set in the periphery of steel pipe 6, and are sealed by barras sealing device 8, and barras sealing device 8 prevents when steel pipe sandblast operation that the sand powder from withdrawing from the mouth from steel pipe screw thread sand-blasting machine 1 and overflows.Air exhauster 2 is communicated with getter device 7 by exhaust pipe 3, and blowning installation 5 is provided with the annular inflatable mouth towards getter device 7 directions.After steel pipe 6 sandblasts are finished, when steel pipe is prepared to withdraw from, start blowning installation 5 and getter device 7, compressed air line 4 enters in the sky bag of blowning installation 5, make the interior high pressure conditions that forms of sky bag of blowning installation 5, the circular curtain that forms together uniformly, sprays to getter device 7 directions by annular inflatable mouth, with the sand powder that the sticks to steel tube surface steel pipe that blows off, getter device 7 will float on airborne sand powder suction exhaust pipe 3 and deliver to air exhauster simultaneously, and the recirculation system sand powder of the sand powder being sent into sand-blasting machine by air exhauster utilizes system.
Blowning installation 5 need not to replace for the different size steel pipe with getter device 7; The steel pipe specification that barras sealing device 8 adapts in the certain limit when needing to change, only needs integral body to change, and changes simple and convenient.
Withdrawing from mouth sealing device with conventional steel screw thread sand-blasting machine compares, the utility model good sealing effect needs to change the parts of maintenance seldom in the whole device, simple in structure, reliability is high, maintenance cost is low, the I﹠M that is conducive to device, the steel tube surface after the sandblast adheres to without the sand powder.
Description of drawings
Fig. 1 is side view of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is Local map of the present utility model.
Among the figure: 1 steel pipe screw thread sand-blasting machine; 2 air exhausters; 3 exhaust pipes; 4 compressed air lines; 5 blowning installations; 6 steel pipes; 7 getter devices; 8 barras sealing devices.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Steel pipe screw thread sand-blasting machine of the present utility model withdraws from mouth sealing device, usually is arranged on the Production Line of Pipe Finishing sand-blasting machine and withdraws from port part, realizes the sand powder sealing of steel pipe screw thread sand-blasting machine is collected.
Steel pipe screw thread sand-blasting machine withdraws from mouth sealing device, mainly partly is comprised of air exhauster 2, exhaust pipe 3, compressed air line 4, blowning installation 5, getter device 7, barras sealing device 8 etc., and compressed air line 4 stretches in the blowning installation 5.Blowning installation 5 and getter device 7 are set in the periphery of steel pipe 6, and are sealed by barras sealing device 8, and barras sealing device 8 prevents when steel pipe sandblast operation that the sand powder from withdrawing from the mouth from steel pipe screw thread sand-blasting machine 1 and overflows.Air exhauster 2 is communicated with getter device 7 by exhaust pipe 3, and blowning installation 5 is provided with the annular inflatable mouth towards getter device 7 directions.After steel pipe 6 sandblasts are finished, when steel pipe is prepared to withdraw from, start blowning installation 5 and getter device 7, compressed air line 3 enters in the sky bag of blowning installation 5, form high pressure conditions, the circular curtain that forms together uniformly, sprays to getter device 7 directions by annular inflatable mouth, with the sand powder that the sticks to steel tube surface steel pipe that blows off, getter device 7 will float on airborne sand powder suction exhaust pipe 3 and deliver to air exhauster simultaneously, and the recirculation system sand powder of the sand powder being sent into sand-blasting machine by air exhauster utilizes system.The barras sealing device plays insulating effect, and by this cover sealing device, the steel tube surface after the sandblast adheres to without the sand powder.
Blowning installation 5 need not to replace for the different size steel pipe with getter device 7; The steel pipe specification that barras sealing device 8 adapts in the certain limit when needing to change, only needs integral body to change, and changes simple and convenient.
Withdraw from mouth sealing device with conventional steel screw thread sand-blasting machine and compare, the utility model good sealing effect needs to change the parts of maintenance seldom in the whole device, and is simple in structure, reliability is high, maintenance cost is low, is conducive to the I﹠M of device.
